Construction of substructure / Mohamad Hakim Mohamad Hatta

The structure of the building is divided into two parts. The sub-structure and the super structure. The lower portion of the building which transmits the load of the super structure to the foundation soil is called sub-structure and the portion of the building which is above the substructure is called super structure. The weight of superstructure is borne by the foundation hence the foundation should be strong enough to carry the load of the super structure. The foundation of sub-structure distributes the load of the building evenly on the soil in such a way that at not below the foundation the soil pressure exceeds the maximum allowable bearing capacity of soil. It helps in strengthening the building against the lateral forces caused due to tornado, earthquake and etc. It provides strong surface for the construction of proposed structure. To provide safety to the structure from flow of water and seepage.
